Hydraulic ram



JAMES OLIVER KAFADER, OF FORT BIDWELL, CALIFORNIA.

HYDRAULIC RAM.

Application filed August 16, i918.

To all whom t may concern Be it known that I, JAMns @Liver Kara- Dnr., a citizen oi' the United States, and a resident of Fort Bidwell, in the county oi' Medoc and State of California, have invented a new and Improved Hydraulic Ram, ol' which the following is a description.

My invention relates to hydraulic rams and although capable of a wider use is more particularly intended for installation in connectioii with subterranean water stratums at diiierent levels.

The general object of my invention is to provide a hydraulic ram adapted to be installed in a cased well extending between subterranean stratums that is the upper and lower levels oi' rise of the water in a well.

Another important object of my invention is to provide a hydraulic rain in which the impetus valve will be so controlled as to cause the valve to be positively lifted to effect the intermittent opening thereof for the discharge of the motive column beyond the air chamber et the ram, as well as to provide a lift means for the impetus valve extending to the top or the well in which the ram is installed and adapted to be adjusted to insure the opening and closing of the valve as well as its proper timing with the discharge of the water through the ascension pipe.

Reference is to be had to the accompanying drawings forming a part of this speci-` ication7 it being understood that the draw ings are merely illustrative of one example of the invention.

Figure 1 is a vertical section of a ram installed in a cased well between two indicated subterranean water stratums;

Fig. 2 is an enlarged side elevation of the equalizer controlling the lift for the impetus valve;

Fig. 3 is a fragmentary view showing in side elevation the valved fitting at the lower end of the ram and connecting the drive pipe with the air chamber, the view being taken in a plane indicated by the line 3-3, Fig. 1;

Fig. 4L is a cross section at the base of the air chamber, the section being taken in a plane indicated by the line number 4l in Fig. 1.

In carrying out my invention in accordance with the illustrated example the ram is installed in a well casing 10 extending be- Speccation of Letters Eatent.

tween an upper subterranean water stratum A- and a lower stratum A. The drive pipe 1l of the ram in which the hydrostatic column or motive column is produced is sus pended from the closed upper end 1b oi' the well casing7 said pipe being open for the inliow of water from the stratum A. rThe drive pipe 11 is secured at its lower end to a fitting 12 having a branch 13 leading to the air chamber lil from which the ascension pipe 15 rises, the inlet to the air chamber `from the passage 13 being controlled by a check valve 16 in the usual manner. rlhe ascension pipe 15 extends through the top 10L of the well casing and rises above the ground level.

The impetus valve 18 in my improved rain instead of opening downwardly as usual in hydraulic rams, liits in the opening movement and close.l by a downward movement. The seat 17 ot the impetus valve is in the fitting l2 directly inline with the vertical drive pipe 11 and has a stem 19 extending upwardly through said drive pipe and above the ground level. The upper end of the valve stem 19 isconnected with one end oi an equalizer bar 2O pivoted between its ends in any suitable manner as on a standard 21 and the opposite end ot the lever is subject to a retractile spring 22 sccured tothe base 21ZL oi the standard, the upper end of the spring engaging a threaded hook 23 having a wing nut 23a or the like to raise or lower said hook Jfor varying the tension of the spring. A set screw 24 in the equalizer bar 20 is adapted to bear against a stop 25 on the standard 21 to limit the movement of said bar 20 in one direction underV the action of the spring 22.

ith the described construction in accordance with the principle of hydraulic rams, the impetus valve 18 will be closed by the tlow of the motive column in the drive pipe 11 but the tension of the spring 22 will be suiiicient to lift the 'said valve and open the same upon cessation of flow ot the motive column following a discharge into the air chamber 14. Thus, upon each period of rest of the motive column, the pressure of the spring will lift the impetus valve permitting discharge of water therefrom beyond the air chamber and cause the intermittent discharge into the air chamber in the well-l nown manner of hydraulic rams generally. Thus7 the positive opening of tween subterranean water stratums.

A vent pipe 26 extends through the top l()a of the well casing l0 for the intake or escape of air due to the rising or falling of water in the well casing bythe discharge through the fitting l2 by the opening of the valve I8.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myselfstrictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without de parture from the spirit of the-invention as deiined in the appended claimsn Having thus` described my invention, I claim as new, an desire to secure by Letters Patent: Y l

l. A hydraulic ram including a drive pipe having an open upper end and adapted to form a hydrostatic motive column, a valve- Controlled air chamber communicating with said drive pipe, an ascension pipe rising trom the air chamber, an impetus valve controlling the intermittent discharge oi' said drive pipe beyond the air chamber and adapted to be closed by the low of the motive column, said valve opening upwardly, and spring actuated means to positivelylift said valve, said lift means being subject to a cessation of flow of the motive column; together with a well casing adapted tobe installed between upper and lower subterranean water stratums, said casing having its upper end closed and from which closed end said drive pipe is suspended and through which the ascension pipe extends, said lift means being arranged above the well casing.

2. A ram including a drive pipe having an open upper end, an air chamber communicating with said drive pipe, an ascension pipe rising from the air chamber, a

well casing adapted to be installed between. upper and lower subterranean water stratums, said casing having its upper end closed and from which closed end the drive pipe is suspended and through which the ascension pipe extends, an impetus valve controlling the discharge from the drive pipe below the connection of the air chamber,-

stalled between upper and lower subter-V ranean water stratums, a pipe suspended from the closed upper end of the casing and having an open upper end, a valve casing at the lower end of the pipe and having a valve seat and a branch member, an air chamber secured to the branch member, a valve in the bottom of the air chamber, a discharge pipe leading from the air chamber out through the top of the casing, a

valve in said valve casing. a spring actuatedv member at the ground level, and a rod connecting the said member with the last named valve. y f
